NSW driver charged over fatal crash

Police have charged a learner driver who had his licence suspended for drink-driving just a day before he was involved in a fatal crash in Sydney's west.

A 34-year-old man from St Mary's died in the crash involving three cars on the Great Western Highway in Prospect shortly before 1.30am (AEST) on Tuesday.

The 28-year-old male driver of one of the cars was taken to Westmead Hospital for minor injuries.

Police later found the man's learner licence had been suspended for high range drink-driving in the 24 hours before the crash.

The man was arrested on Wednesday afternoon and charged with dangerous driving occasioning death, negligent driving occasioning death, driving while suspended and being an unaccompanied learner driver.

He has been refused bail and will appear at Parramatta Local Court on Thursday.
